Physical vapor deposition (PVD) is a thin-film coating process that produces coatings of pure metal, metal alloys and ceramics with thicknesses typically in the range of 1 to 10 µm.
Plasma nitriding (plasma nitriding) is a plasma-assisted thermochemical hardening process that improves wear resistance, surface hardness, and fatigue strength by forming a hard layer containing co
